OUR COMPANY &

OUR STRATEGY

A NOTE FROM ROB SALTIEL, PRESIDENT & CEO

MRC Global is the largest distributor, based on sales, of pipe, valves and fittings (PVF) products and related infrastructure supplies and services to the energy and industrial sectors of the global economy. Our business mix is diversified by region, industry sector and product line. We are a multi-cultural team of over 2,600 dedicated employees with facilities in 17 countries. We are committed to the success of our customers, our communities and each other.

The four main business sectors we serve are: Gas Utilities (storage and distribution of natural gas), Downstream and Industrial (crude oil refining, petrochemical/chemical processing and general industrials), Upstream Production (exploration, production and extraction of oil and gas), and Midstream Pipeline (gathering, processing and transmission of oil and gas). In addition to our traditional focus on oil and gas, our end use-markets also include mining, chemicals production, desalinization plants, pulp and paper processing, power utilities, green energy projects and other industries.

As a distributor of PVF, we sell products that control the flow of liquids and gases in a safe and environmentally responsible manner that minimizes impacts on our air, water and soil. Our customers specify their PVF products to limit the greenhouse gases (GHGs) that their operations emit. For instance, 94% of the valves we sell are designated as "Low-E" (i.e., low emission) because they prevent unwanted leaks of harmful GHGs such as methane or carbon dioxide. In addition, the pipe, fittings and flanges that MRC Global provides are differentiated by metallurgy, pressure rating, temperature rating, and other requirements to transport fluids and gases safely without leaks or pollution.

MRC Global's corporate strategy is focused on sustainable growth, margin enhancement, and the development of long-term customer relationships within the markets we serve.

Our strategic objectives are to:

• increase market share in our four main business sectors through superior customer service and new value-added offerings

• diversify our product and service offerings to serve attractive new industry sectors, including those related to the energy transition
• invest in technology systems and distribution warehouse infrastructure to improve operational efficiency and customer reach
• deliver attractive returns for our shareholders through optimization of our inventory mix and working capital

A global energy transition is underway to address climate change, and we expect that this will have significant impacts on MRC Global's future business. We believe that our company has an important role to play in the energy transition, and we are already participating in many green energy projects and decarbonization efforts. In recent years, we have supplied PVF products for use in biofuel, wind, hydrogen, geothermal, hydro-electric and carbon capture and storage projects. As of this writing, we are competing to participate in various green energy and decarbonization projects around the globe.

While the energy transition is inevitable, we believe that carbon-based energy will continue to play a critical role in supporting economic growth and human quality of life, particularly in developing countries, for the next few decades. Many of our largest customers are among the leading investors in green energy and decarbonization technology. As they further rebalance their capital investments toward green energy sources, we expect to enhance our product and service offerings to support their changing requirements.

In summary, MRC Global will continue to leverage our company's 100-year history of serving the oil and gas industry by providing our customers with critical pollution prevention equipment for their operations. At the same time, we will work to establish MRC Global as the leading PVF provider to the rapidly expanding energy transition and decarbonization space. We believe that our skills, assets and experience will position us for success in both arenas, and I am confident our employees are up to the task.
